Cosmological Perturbations During Radion Stabilization
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
We consider the evolution of cosmological perturbations during radion stabilization, which we assume to happen after a period of inflation in the early universe. Concentrating on t…
Boundary Inflation in the Moduli Space Approximation
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
The evolution of slow--roll inflation in a five--dimensional brane world model with two boundary branes and bulk scalar field is studied. Assuming that the inflationary scale is be…
Inflationary Dynamics with Runaway Potentials
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
The evolution of two slow--rolling scalar fields with potentials of the form is studied. Considering different values of the parameters , and ,…
Suppression of Entropy Perturbations in Multi--Field Inflation on the Brane
P. R. Ashcroft, C. van de Bruck, A. -C. Davis
At energies higher than the brane tension, the dynamics of a scalar field rolling down a potential are modified relative to the predictions of General Relativity. The modifications…
